Ok so I got a shop to install a 5 inch step vrsf fmic and on the way home i did a couple wot on 2nd and 3rd gear. When i got home i open the hood with the car still on and got a whining or humming noise that comes and go on the passenger side of the engine. Car seems to idle normal still and do feel a little bit stronger now. No codes are thrown. Not sure what it is. Taking the car back to the shop when i got time for now it will be park in the garage. Anyone experience this or know what it may be before i take it to the shop in the next couple of days.

Car is all stock with just the vrsf fmic and cobb tune on stage 1 drive and now is on cobb tune stage 1 +fmic drive since i am from CA and gas sucks here. Car only been tuned for 1 week before putting the fmic in and spark plugs only got like 2k miles on them prior to having it tune. Both turbo been replaced under warranty like 4k miles ago.

Click on video below to listen to the noise.

It sounds like the FMIC is vibrating against another part of the car.
Maybe check all clearances around the FMIC.

Thats what i was thinking also

Can't hear video but it could be boost solenoids which would just coincidental.

If there is anything I noticed with FMIC installs, it's those clamps typically need adjustment after a few pulls sometimes, more so related to boost leaks.

With a flash light you should be able to check clearances on the pre inlet tubes.

Just double checked and video works with sound. Did a search and seems like people having same issue and is the boost solenoid. I will check into that first. Dont seem like there is any running and all clamps are tight in place.

When I click the video it says it's been renamed or deleted by it's owner. Perhaps only you can see it since it's your photobucket account.

Is it set to private.

Eitherway, boost solenoids are common on making noises.

Giving them a light tap while humming sometimes fixes it temporarily.

If it acts up again, it usually means its time to replace them.

Does the noise change at all as you give it some gas?

Yeah is boost solenoid. Goes away when i tap it and comes back in fourth.
